To aZZu-Fwmitmay concern: Be it-lznown that l, CALvIN R. DAVIS, a citizen of the United States, residing at Chicago Heights, in the county of Cook a and State oflllinois, have invented certain new and useful Improvements in Manure- Edpreaders, of which the following is a speci lication.

This invention relates in general to ma- 1o nure spreaders, and has more particular reference to the distributing mechanism by means of which the manure or fertilizer is distributed over the ground as the machine travels along.

35 One of the primary objects of my present invention is the provision of a novel and improved distributing device which, in conjunction with the usual delivery cylinder, will thoroughly and evenly distribute the Z manure from the machine over an area of greater width than the width of the machine.

Another object is to provide a distributing device which will satisfactorily distribute all kinds of manure or fertilizer, and will not clog or wind up with straw, marsh grass or corn stalks contained in the manure, but which is so constructed asto present no straight edges or sharp corners upon which 8O straw, hay or corn stalks might catch, or

about which they might wind; the device being so constructed as to present only curved surfaces and edges to the material being distributed.

A further object is to provide a distributing device having distributing blades of novel construction so arranged and positioned as to throw the-material being spread laterally beyond the wheels of the machine, to and also constructed so as to free themselves readily from the material and permit the material to be thrown and distributed freely without retentionby the blades. My invention and its. mode of operation will probably be best-understood by reference to the following description, when considered in connection with the accompanying drawings, throughout the various figures of which like reference characters refer to similar parts.

Referring to the drawings,Figure 1 is a rear end view of a manure spreader embodying my invention; Fig. 2 is a fragmentary side elevation looking toward the right 95 at the construction shown in Fig. 1; Fig. 3 1s a longitudinal sectional view through the machine; and Fig. 4 is a detail perspective view of one of my improved distributing blades.

-On the drawings, reference character 5 indicates a portion of the main frame of the machine, supported at its rear end upon a main shaft 6 carried by a pair of wheels 7.- lhe front end of the machine (not shown) 1s supported upon wheels arranged in any well known or preferred manner. The bottom of the machine comprises an endless slatted conveyor 8 trained around a sprocket wheel 9 fixed on a shaft 11, upon which is mounted a worm wheel, 12 adapted to be driven by a Worm 13 carried -on a shaft 14, which shaft is equipped at its other end with a bevel gear 15 adapted to mesh with and be dr yen by a companion gear 16 fixed on the mam shaft 6.

Adelivery cylinder 17 of well known constructlon, is mounted upon a shaft 18 rearwardly of and above the bottom conveyor- 8, this delivery cylinder being driven in a clockwise direction viewing Fig. 3, through the instrumentality of a pinion 19 fixedon the shaft 18 and driven by a gear 21, which in turn is connected with a sprocket wheel 22 adapted to be driven by means of a chain 23 from a drive sprocket-wheel 21 fixed on the shaft 6, as shown in Fig. 1.

The mechanism'thus far described may be of any Well known or preferred construction, and the details thereof are not comprehended in my present invention.

It is desirable in orderto secure the best results from the fertilizer applied to the land that it be finely divided and evenly distributed over the ground. It is also desirable to spread the manure over an area of liver the manure rearwardly and laterally of the machine, so that it becomes finelv distributed over an area greater in width than the machine. I have therefore equipped the rear end of the frame members 5 with upwardly-extending supporting members 25 carrying suitable bearings 26, in which a of distributing blades arranged in spiral relatien on the periphery of said cylinder, each of said blades presenting acurved outer edge increasing from front to rear in radial distance from the cylinder axis and a curved rear face. I

5, A distributing device for manure spreaders comprising a cylinder provided on its periphery with a series of obliquely disposed blades, each blade having a concave rear working face and a curved outer edge.

6. A distributing device for manure Spreaders, comprising arotatable cylinder and a plurality of blades arranged thereon,

each of said blades being constructed to pre sent a smooth curved edge in the direction of travel, increasing in radial length from front to rear and also dished circumferentially of the cylinder to present a concave in contact.

7.1K distributing device for manure spreader-s, comprising a rotatable cylinder provided on its'periphery With a series of substantially triangular blades of maximum radial length at their rear ends, tapering in a curve to the periphery of the cylinder at their forward ends, said blades being secured along one edge to the periphery of the cylinder and arranged upon the cylinder obliquely to the axis thereof so as to present smooth edges to which the material Will not cling, and inclined faces for distributing the "niateriai laterally. r
